Composite of size-controllable metal nanoparticales and the method of making the same

Abstract

A method of synthesizing size-controllable metal nanoparticles includes the following steps: a) Preparing an exfoliated silicate clay solution and a metal ion solution; and b) Mixing the exfoliated silicate clay solution with the metal ion solution, and the metal ions are reduced to the metal nanoparticles, which are attached to the exfoliated silicate clays. Additionally, in step A, adjust the weight ratio of the silicate clays to the metal ions to control the size of the reduced metal particles. And with larger weight ratio of the silicate clays to the metal ions, the size of the reduced metal particles becomes smaller.
